Former Olympic track star Marion Jones has little doubt about it — she believes that Usain Bolt is the sport’s greatest star. Ever.

“I certainly think based on the fact that he’s still so young and that he’s already accomplished so much that, barring serious injury or anything else, I think that he certainly would be considered the greatest track and field athlete ever,” Jones told The Associated Press in a phone interview Wednesday.

“And that’s based on the fact that he’s so young. This is not a person who’s 34 or 35 years old. He’s young, he’s vibrant, he sees that there’s so much left for him to do in the sport. People might not say that. People might say, ‘He already has the world record. How much faster can you go?’ But when you’re young, you think differently than a lot of people. You think the sky is the limit.”

Jones, who expects Bolt to win the 200 meters on Thursday, said it’s more than his accomplishments on the track that set the Jamaican star apart from the elite.

“I think the reason that he has emerged into such a star, it’s certainly more than just the fact that he can run super fast,” Jones said.

“There have been so many athletes in the history of track and field that have accomplished that, but it’s everything else that he brings to the table. It’s the excitement, it’s the bravado … it’s the swag that he has prior to the race, after the race. It’s almost like it does not faze him.”
